The simulation of dental fluorosis

Published: 26 August 2005 Publication History

Abstract

Dental fluorosis occurs when excess fluoride is incorporated into the enamel of developing teeth, resulting in a mottled appearance on eruption. The effects can range from mild white striations to more severe pitting and staining. In recent years there has been an increase in the prevalence of dental fluorosis, which is probably linked to an increase in fluoride intake during tooth development. One of the key questions in dental public health concerns the appropriate level of exposure to fluoride at a young age. There is clear evidence that water fluoridation is associated with a decrease in the prevalence of tooth decay, but this health benefit has to be weighed against the potential side effects, one of which is dental fluorosis. Outside areas of naturally high water fluoride levels fluorosis is almost invariably mild, but relatively little is known about the true aesthetic impact of this condition, especially amongst the general public. Previous research on public perception of mild fluorosis is unconvincing due to the use of unrealistic images in the assessments (see Edwards et al. [2005]). We used realistic views of a single model with healthy teeth and then digitally modifying the teeth to simulate the appearance of dental fluorosis. These images were then presented to teenage members of the general public via a web-site interface and their appearance was rated using a questionnaire.
